Astatistician is waiting behind one person to check out at a store. the check-out time for the first person, x, can be modeled by an exponential distribution with some parameter λ > 0. the statistician observes the first person’s check-out time, x; being a statistician, she surmises that her check-out time y will follow an exponential distribution with mean x.

hope this : )

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

this is a good question! i'll do some research and come back when i have the answer!
